Window#
This is the benchmark for measuring the overhead of an
MPI_Win_create/MPI_Win_fence/MPI_Win_free
combination. In the case
of an unused window, a negligible non-trivial action is performed inside
the window. It minimizes optimization effects of the MPI implementation.
The MPI_Win_fence
function is called to properly initialize an
access epoch. This is a correction as compared to earlier releases of
the Intel(R) MPI Benchmarks.
See the basic definitions and a schematic view of the pattern below.
